Abstract
The utility model aims to provide a reflecting demonstration device of light for teaching use, which comprises a housing. The housing, being a transparent container, is provided with light showing liquids inside. A flat mirror is provided in the bottom of the housing whose top is provided with a light source fixing base. The utility model is characterized in the simple structure, convenient operation, and clear direct demonstration effects.
Description
Technical field
The utility model relates to the teaching light reflection demonstrator.
Background technology
Existing teaching demonstration reflection of light process adopts a level crossing to demonstrate mostly, but can not clearly see the whole route of light clearly this process middle school student, can only see the position of several luminous points, can not directly form the position relation of line and face, some teacher places a baffle plate in the position near the circuit that is parallel to light in the process of demonstration reflection of light, making a part of light and baffle plate intersect drops on the baffle plate, another light branch passes through flat mirror reflects, grasp but the position of baffle plate is difficult in this process, and incident ray and reflection ray can not drop on the baffle plate simultaneously, can not directly reflect the position relation of incident ray and reflection ray.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, easy to operate, the demonstration effect is clear, light reflection demonstrator is used in teaching intuitively.
To achieve these goals, technical solution of the present utility model is such: a kind of teaching light reflection demonstrator, comprise the housing of teaching with light reflection demonstrator, described housing is a transparent container, light is housed in the described housing shows liquid, housing bottom is provided with level crossing, and case top is provided with the light source holder.
Because in the above-mentioned technical solution, housing is a transparent container, and light is housed in the housing shows liquid, such structure can be known the circuit that demonstrates incident ray intuitively, and housing bottom is provided with level crossing, the reflection ray that incident ray comes out by flat mirror reflects equally also can be clear that, and by observing and clearly to find incident ray and reflection ray at grade with the side of light reflection demonstrator from teaching, it is for fixed light source that case top is provided with the light source holder, thereby the operation of convenient whole presentation process, so the teaching that the utility model provides has simple in structure with the reflection of light demonstration device, easy to operate, the demonstration effect is clear, characteristics intuitively.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of the teaching that provides of the utility model with light reflection demonstrator.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Wherein: 1, housing; 2, light shows liquid; 3, level crossing; 4, protractor; 5, light source holder.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3, the utility model provides a kind of teaching light reflection demonstrator, comprise the housing 1 of teaching with light reflection demonstrator, described housing 1 is a transparent container, light is housed in the described housing 1 shows liquid 2, housing 1 bottom is provided with level crossing 3, and housing 1 top is provided with light source holder 5, and this teaching has simple in structure, easy to operate, clear, the characteristics intuitively of demonstration effect with the reflection of light demonstration device.
As Fig. 1, Fig. 2, shown in Figure 3, a protractor 4 is erect in described housing 1 bottom, the protractor of erectting 4 can clearly show the angle of incident ray and reflection ray, and the angle of demonstration incident ray and the angle corresponding relation of reflection ray are played effect more intuitively.
